Country extensionSince 1991

.co domain registration

Two short letters many read as “company”: Colombia’s extension, which its operator presents as short for company, for startups and new projects, and a close alternative when your name is taken in .com.

Overview

What is .co

.co entered the internet’s root in 1991 as Colombia’s extension, and its manager in the IANA record is Ministry of Information and Communications Technologies (MinTIC), Colombia’s communications ministry. Since 3 October 2025 the CentralNic registry, of the Team Internet group, has run it on the ministry’s behalf, presenting it as short for company or corporation.

.co doesn’t require you to be in Colombia: anyone, person or company, from any country, can register it, with no documents. That is why entrepreneurs and startups choose it when they want a short name read as “company.” It supports DNSSEC signing, but it has no table for Arabic letters in IANA’s records.

What you should know: its price with us is higher than .com, though fixed every year, and a registration in it runs from one year to five, not ten. And whoever forgets your extension may type .com out of habit, so some of your email and visitors reach the name’s owner there.

Who it suits

For your field: is .co the best fit?

Every field has an extension that says something about it. Here is what .co says in each, and which extension completes it.

  • A startup

    Excellent · A strong choice

    Two letters investors and customers read as “company”; a short name is easier to find in it than in .com; add .io for a tech product.

    Register it with.co.io

  • A company or brand

    Good · A good fit with .com

    It says “company” in two letters; but whoever forgets your extension types .com, so register that too if you find it free.

    Register it with.co.com

  • A short campaign link

    Good · A good fit

    Two letters after the dot leave room for your campaign’s word, so the link stays short on the ad and the post.

    Register it with.co.link

  • A local business in Saudi Arabia

    Good · A good fit with .com

    .co says “company” in two letters, but your customer in Saudi Arabia types .com out of habit; register both.

    Register it with.co.com

  • An association or initiative

    Consider another · Consider .org

    .co reads as “company,” while donors and volunteers trust .org; add .community for an initiative that brings people together.

    Register it with.org.community

  • A blog or personal site

    Consider another · Consider .me

    Your personal site doesn’t need to say “company”; .me says it’s yours, and .blog that it’s a blog.

    Register it with.me.blog

What it does for you

What you gain when you register it

  • Says “company” in two letters

    Many read .co as short for company, so it places you among businesses at first sight.

  • More short names available

    A short word for your project is easier to find in it than in .com.

  • Short email

    hello@manassa-riyadh.co is a short address that fits on the card and reads easily.

  • A country code with no conditions

    Though it’s Colombia’s extension, anyone, person or company, from any country can register it, with no documents.

And where its value shows

In the investor pitch

A short name on the first slide.

On the business card

Two letters after the dot that don’t crowd your name.

In campaign links

A short link that’s clicked and remembered.

In your email signature

Your company’s address, short and neat.

Tips

Before you register

  1. 1Write .co clearly in your adsOnly one letter separates it from .com, so write it clearly and say it as “dot co.”
  2. 2A name that works in Arabic and EnglishPick a name before .co that’s easy to read and say in both languages, so your customer in Saudi Arabia writes it as they heard it.
  3. 3A short name, read as it’s writtenIf it needs spelling out on the phone, it’s too long or too complicated.
  4. 4No digits or hyphens that need explainingEvery hyphen or digit has to be said, and what has to be said gets forgotten.
  5. 5Renew automatically, or register for yearsUp to 5 years at once, so you never miss a date.
  6. 6Make sure the name isn’t someone else’s trademarkA registered trademark’s owner can recover the name from whoever registered it first.

  • $49 a year, for the first year and every renewal: the price you see when you search, with no other fees at registration.

  • Anyone, person or organization, from any country, with no documents and no address in Colombia.

  • Yes, once 60 days have passed since it was registered or last transferred: ask your current provider for the transfer (EPP) code and open a transfer request with us. The transfer adds a year to its term.

  • The .co registry allows a renewal grace period of up to 45 days after expiry, within what the registrar allows. If the name is deleted, it can be redeemed within 30 days for a redemption fee; then it is deleted for good after 5 days and is free again.

  • No. IANA’s repository of internationalized names (IDN) holds no Arabic table for .co, so names in it use Latin letters, digits and hyphens.
